Detailed studies of electromagnetic and hadronic showers in a SiPM-on-tile highly granular calorimeter — •Olin Lyod Pinto for the CALICE-D collaboration — Deutsches Elektronen-Synchrotron, Hamburg, Germany

The analog hadron calorimeter prototype is a highly granular calorimeter based on steel absorbers and SiPM-on-tile readout, developed by the CALICE Collaboration. It has acquired sizeable data sets with precise five-dimensional information on electromagnetic and hadronic showers in two test beam periods at the CERN SPS beam test facility. The unprecedented granularity of the detector provides detailed information about the properties of electromagnetic and hadronic showers, which helps to constrain shower models through comparisons with model calculations. Results on longitudinal and lateral shower profiles compared to GEANT4 shower models will be discussed which were measured for electrons and pions in the energy range 10 - 100GeV. The comparison of longitudinal and lateral shower profiles to simulations with a variety of different hadronic shower models can provide input for further development of these models.
